Ravenna FIS Incinerator

Located in the Baiona Ecological Centre, Via Baiona Ravenna

  • 1 / 1   Ravenna FIS Incinerator

The plant, located in the Baiona Ecological Centre in Ravenna, is designed for the combustion of non-chlorinated gaseous emissions coming from the production plants of the Chemical Industry District of Ravenna.

The plant was created under the scope of the Memorandum of Intent of 22.04.1997 between the municipality, Province and companies in the Chemical Industry District of Ravenna to reduce the flow of VOC given off into the atmosphere through the incineration of gaseous emissions using gas flaring.

    The gas incineration plant comprises a vertical combustion chamber covered in a refractory material. It is self-supporting and fuelled by a burner into which the gases to be treated are conveyed.

    1 - Receipt.
    The gaseous effluents to be treated, which come from the neighbouring petro-chemical district, are accepted up to the battery limit of the Ecological Centre and conveyed to an underhead hydraulic seal.

    The hydraulic seal has the dual function of collecting any condensates and preventing the risk of flash back to the flare circuit. The effluents flow from the hydraulic seal to the combustion chamber burner via two blowers.

    2 - Combustion.

    The fumes leaving the combustion chamber at a temperature of between 850°C and 1000°C, depending on the incinerator operating conditions, are evacuated through a chimney with a refractory liner positioned at the top of the chamber and connected to it by means of a suitable connecting cone. The self-supporting chimney is approximately 14 metres high, which ensures that the fumes are released at a height of 30 metres above ground level. There are several air vents on the chimney for cooling the fumes to a temperature of between 600°C and 750°C.

    3 - Fume purification.

    The gaseous current produced by combustion, comprising CO2, H2O and nitrogen, is discharged directly into the atmosphere at a minimum temperature of 600°C.

    Gases emitted into the atmosphere are monitored through a continuous Emissions Monitoring System (EMS), in accordance with existing regulations and the Integrated Environmental Authorisation (IEA). The CO, COT and NOx parameters are continuously analysed. The monitoring programme implemented was approved as part of the current IEA.
